The role of frequency conversion technology in work equipment - Reynolds
Because inverters are widely used, there are many differences in the corresponding types and specifications. We are broadly divided into two categories: voltage and current. The current type of inverter products is characterized by the use of a large inductor as the energy storage link in the middle DC link, and the reactive power will be buffered by this inductor. ...

Advantages of frequency converters over soft start – Reynolds
(1) The starting torque is large and the power factor is high. Because the power factor of the motor is related to the working frequency, the power factor under the power frequency power supply is much lower than that under the low-frequency power supply when the motor is running at low speed. The inverter can control the motor from low frequencies and ...

The reason for using frequency conversion speed regulation - Reynolds
Variable frequency speed regulation can be used in most motor drag occasions, because it can provide accurate speed control, so it can easily control the rise, descent and variable speed operation of mechanical transmission. The use of frequency conversion can greatly improve the efficiency of the process (the variable speed does not depend on the mechanical part) and at the same time ...

The factor that causes the breakdown of the inverter – Reynolds
1. Overpressure leads to brake pipe breakdown.
The so-called overvoltage of the inverter refers to the fact that the inverter voltage formed due to various reasons exceeds the additional voltage, which is concentrated in the DC voltage of the inverter DC bus.
The overvoltage alarm generally appears at the time of shutdown, and its main ...

Reynolds drive safety rules and warnings
The high-voltage inverter has been designed with the safety of the user in mind. However, due to the energy storage capacitor installed inside the power unit of the inverter, it may still carry a high voltage after disconnecting the power supply, and some parts generate a lot of heat, so contact is prohibited. When working on or near the inverter, please ...

The cause of bearing noise in different situations of frequency converters - Reynolds
1. If the bearing is in good continuous rotation condition, it will emit a low whining or humming sound. Sharp hissing, squeaking and other irregular sounds often indicate that the bearing is in a bad continuous rotation condition. The sharp squeaky noise can be due to the formation of an inappropriately smooth ...

Tips for using reducers - Reynolds
1. After 200-300 hours of operation, the first oil change should be carried out, and the quality of the oil should be checked regularly in the subsequent use, and the oil mixed with impurities or deteriorated oil must be replaced in time. Under normal circumstances, the reducer for long-term continuous operation should be replaced after 5000 hours of operation or once a year.
